Villain's Odyssey: Enslaving heroines, Conquering Villainesses

I was betrayed in my first life. A cripple, broken and discarded— I died after catching the one I loved in bed with the only person I ever called a friend. That was the start of real torment. When I woke up, it was in another world. A goddess stood before me. She told me I could go back. Back to my world. Back to everything I lost. All I had to do… was play my part. The side character. And I did. I followed the script. Played my role to perfection. They hated me. Mocked me. Used me. Again and again. But I kept going. Because I believed her. Because I wanted to go home. Then one day, I found out. The hard way. It was all a lie. There was no going back. There never was. She used me. Again. Just like everyone else. Thrown away like trash once I outlived my usefulness. That was the day something inside me snapped. And so, I made a vow. I would take everything from her. I would enslave every single heroine she chose. And I would kill the hero she placed all her hopes on. If she wanted to protect this world… Then I would burn it down. But the more I tried, the more things started to change. And then one day— I found one of the heroines. One of the hero's yanderes I had enslaved. She stood there, trembling, a knife in her hand. “You’re not going anywhere,” she whispered, eyes wild. “I won’t let them have you. You belong to me.” ...What. The. Fuck. Is. Happening?!
